MCQ
The mean for the data $6, 7, 10, 12, 13, 4, 8, 12$ is:
  • ✓
    $9$
  • B
    $8$
  • C
    $7$
  • D
    $6$
✓

Answer

Correct option: A.
$9$
A.  $9$
Solution:
We have, $x_i = 6, 7, 10, 12, 13, 4, 8, 12$
$\therefore {\text{mean}} = \frac{{\text{sum of all the observations}}}{\text{total number of observations}}$
$ = \frac{6 + 7 + 10 + 12 + 13 + 4 + 8 + 12}{8}$
$ = \frac{72}{8} = {9}$
